Application filed August 9, 1911. Serial No. 643,247.

To all whom it may concern:

Be it known that I, Fern M/Coousun, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Skiving- Machines; and Ido hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming a part of this specification,and to the reference-numerals marked thereon.

My present invention relates to improve ments in skiving machines, beingadapted for use in connection with the skiving of any character of work,and it has for its object to pro'videa novel construction andarrangement of parts whereby the work will not be interfered with by themechanism as it is fed through the machine, and after it is acted uponby the cutter.

A further object of my invention is the provision of a feed disk whichmay be adjusted in its cooperative relation to the feeding roll andcutter.

Still another object of the invention is to provide a work guide, havinga novel means for adjusting its position relatively to the feeding roll.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a view in front elevation of a machine,disclosing one embodiment of the invention; Fig. 2 is a view in endelevation of the same; Fig. 3 is a view in elevation from the oppositeend; Fig. dis a sectional view on the line a:-zv of Fig. 2, the feeddisk and its supporting bracket being removed; Fig. 5 is a sectionalview on the line 7 -7 of Fig.4; Fig.0 is a view in elevation of thefeeding roll and transmitting mechanism therefor; Fig. 7 is a top planview of the machine; Fig. 8 is a sectional View on the line a-a of Fig.7, and Fig. 9 is a sectional view on the line b-?) of Fig. 4.

Similar reference numerals throughout the several figures indicate thesame parts.

In the present construction and arrangement of parts, wherein I haveshown a preferred embodiment of the invention, the machine comprises abase 1, on which is mounted the operating mechanism, the base beingsuitably supported on the frame Slid: ably arranged upon the base 1 isthe stand ard 3 which is movable between the guides 4, and held inadjustedposition by means of the adjustingscrew 5. The standard 3 isprovided at its upper portion with a forwardly extending arm 6 providedat its front end with the bifurcations 7 between which is pivotallyarranged the plate 8, provided with upper and lower bearings 9 and 10,respectively, holding the threaded sleeve 11. within which is rotatablymounted a shaft 12 which carries the cutter 13 and is provided with asuitable pulley 14L arranged intermediate the bearings 9 and 10. Thecutter 13 preferably occupies the position shown in Fig. 1, beingangularly disposed relatively to its cooperating parts, such angularadjustment being susceptible of change in a manner that will bepresently explained, and vertical adjustment of the cutter being securedthrough movement of the threaded sleeve 11 with relation to the bearing9. The plate 8 is provided at its rear end with a toothed segmental edge15 arranged to be engaged by the screw 16 a mounted on the arm 6 andoperatedbythe thumb nut 17. a H

Suitably attached to the bearings 9 and 10 is the bracket 18 which isprovided with bearings 19 and 20, the latter having journaled thereinthe shaft 21 which carries the grinding disk 22 and rotates within asleeve 23 having threaded engagement with the bearing 19, so as toobtain vertical adjust ment of the grinding disk relatively to thecutter. The shaft 21 carries a suitable pulley 2 by which the grindingdisk may be operated in a manner that will be presently made clear. a

In order to obtain proper cooperation between the cutter, feeding roll,and the feed 1 disk, and centering of these parts, it is desirable toprovide some means for obtaining lateral adjustment of the feed diskrelatively to the cutter and feeding roll, as, for instance, to allowfor wearing away of the cutter, and to this endqin the present embodiment, the feed disk, designated at 25, is carried by the shaft 26which is rotatably mounted in bearings 27 formed on the bracket arm 28,the latter being pivoted at 29 to the carrier 30 which is provided withsuitable Ways having engagement with the guides 31 arranged on one ofthe bifurcations 7, as shown in Fig. 9. By this an rangement, the feeddisk may be swung laterally on the pivots 29 to effect its properpositioning, while at the same time, longitudinal movement of thestandard is possible relatively to the feed disk by means of the slidingengagement of the carrier30 With the guides 31. To hold the feed disk inits position of lateral adjustment, an ad-' justing screw 32 is providedfor engagement with the bracket arm 28 which is held relatively to saidscrew by means of the thumb nuts 33. The shaft 26 carrying the feed diskis provided at its upper end with a pulley 34 by which the shaft isrotated as will be hereinafter described, the feed disk being suitablyheld in normal lowered position by means of the spring 35 arrangedbetween the upper bearing 27 and the collar 36 fixed upon the shaft 26.

In order to effect the proper feeding of the work beneath the feed diskto the cutter, there is provided in the present embodi ment the feedingroll 37, which is journaled upon the bearing 38, the latter beingcarried by the post 39, having the base 40 slidably arranged in thetrack 41 on the base, and held in the desired position of adjustment bythe adjusting screw 42'. Lateral movement of the post may be effected inany suitable manner, as by means of the adjusting member 43 which isrotatably mounted on the post 39 and has threaded engagement with thestationary abutment 44.

The feeding roll 37 is provided with a l-iorizontal surface positionedbeneath the feed disk 25, a shoulder 45 adjacent to the horizontalsurface, and a beveled surface extending beyond said shoulder to theopposite side of the feeding roll. Arranged for cooperative engagementwith said beveled portion is the guide 46 Which is carried by the arm47, the latter being formed integral with the sleeve 48 which isarranged upon a support 49, the latter being suitably attached to thepost 39 and arranged parallel to the normal plane of the cutter 13. Thesleeve 48 is held in adjusted position on its support 49 by means of theadjusting screw '50, or in any other suitable manner. The guide 46, aswill be noted from Fig. 1, is arranged to engage the edge of the work,and is provided with an upwardly and for wardly extending box or housing51 within which is arranged a suitable presser foot 52, held inengagement with the work by means of a spring 53'. The presser foot 52is provided with the recess 54 withw'hich cooperates the thumb screw 55for obtaining necessary vertical adjustment; The spring 53 is held inoperative position by means of the thumb screw 56.

The feeding r011 may be rotated from beneath the base of the machine inany suitable manner, this being effected in the present embodiment. bymeans of the shaft 57 arranged beneath the base 1 and carrying thesprocket wheel 58, the feeding roll being provided with a correspondingsprocket wheel 59, and a suitable chain 60 connecting the respectivesprockets.

Journaled upon the standard 3 is the vertically arranged shaft 61carrying the pulley 62 at its upper end, the beveled gear 63 r shaft 66also carries the pulley 68 and friction cone 69, the latter beingarranged for engagement with the friction clutch 70 which is formedintegral with the pulley 71 and is loosely slidable along the shaft 66',such movement of the clutch being effected by vertical movement of thecam lever 72 which engages the stationary cam 73, and carries avertically extending post'74 at its upper end for a purpose to beexplained hereinafter. Pulleys 75 are arranged on opposite sides of thestandard 3, being carried on the vertically adjustable supports 76, andthe cutter is driven by means of the cable 77 which leads from thepulley 68, around pulleys 75, to pulley 14, on the shaft 12, as shownclearly in Figs. 1 and 7. The pulley 71 is rotated by a cable 78 leadingfrom a suitable source of power, and motion is transmitted to the.several parts of the machine from the pulley 71 by moving the frictionclutch 7 0 into engagement with the friction cone 69,'this beingeffected by operation of the cam lever 72 downwardly. When the cam leveris operated in the reverse direction, to effect the release of theparts, it is desirable that some meansbe present for stopping themachine immediately, and to this end, 1 provide a pivoted brake shoe 7 9arranged for engagement with the pulley 68, as shown clearly in Fig. 1,and having a tail-piece 80 which is adapted to be engaged by the post 74on the cam lever, when the latter is moved upwardly.

The feed disk 25 is preferably rotated by means of the cable 81whichleads from 1511i ley 62 to pulley 34, mounted, respectively, onshafts 61 and 26. In order to allow for taking up of any slack in thecable 81 resulting from the longitudinal adjustment of the standard 3, Iprovide the pulley 82 mounted on the adjustable arm 83 and arranged toengage the cable 81, as shown in Fig, 7.

The grinding disk may be rotated in any convenient manner, and in thepresent embodiment, to this end, I provide a clutch face 84: on one ofthe pulleys 75, which is arranged to cooperate with the pulley 85arranged on the same bearing, the latter pulley having the friction cone86 for engagement with the clutch face 8-l-. Asuitable cable 87 leadsfrom thevpulley 85 to the pulley Q-l hereinbefore described, to effectrotation of the grinding disk which is normally idle, when pulleys 7 5and 85 are disengaged. Movement of the pulley 85 to clutch the partstogether may be effected in any desirable manner, as in the presentembodiment, by means of the lever 88 which carries a block 89 arrangedto engage the spindle 90, the latter being hollow and mounted upon thebearing 91 which supports the pulley 75, the pulley 85 being fixed onthe hollow spindle 90, which is held normally away from the bearing 91 aby means of the spring 92.

By the arrangement of the parts as herein shown and described, it willbe noted that a free area is afforded surrounding the feed ing roll, andthe operating point, this being particularly desirable where the machineis operating on a curved or rounded piece of work which turnscontinuously as it is fed, and comes in contact with the frame work oroperating mechanism of the machine, unless such a free area is providedas in the present invention, and while I have described the structure asembodying a standard in spaced relation to the feeding roll, andprovided with an arm extending above and toward the feeding roll andcarrying the feed disk and cutter, it is to be understood that the sameend may be accomplished in other ways without departing from the spiritand scope of this application.

A further important feature of my improvements resides in the provisionof means for securinglateral adjustment of the rotating feed disk bywhich the feed disk, and cutter may be properly centered with relationto the feeding roll and the work, under all conditions, and regardlessof the size of the cutter.

My invention is further chm'acterized by an improved form of work guide,the essential feature of which consists in enabling its adjustment, withrelation to the work, in the direction of the plane of the cutter, andthe invention is not to be limited to the particular means herein shownfor accomplishing this purpose, but contemplates any form of guide thatis capable of adjust ment, in a direction parallel to the plane of thecutting member.
